'Celebrity Rehab' alum Jason Davis arrested for drug possession

So much for sober living.

Jason Davis, the "Celebrity Rehab" castmate who annoyed his fellow rehabbers (and viewers) to no end, but ultimately agreed to go into a sober living facility on the season finale, has been arrested for drug possession.

According to TMZ, Davis was arrested Thursday (Jan. 27) night in Newport Beach, Calif., for possession of a controlled substance. The arrest came just one day after the taping of the "Celebrity Rehab" reunion show, in which Davis claimed to be clean and sober.

He's currently being held on $20,000 bail.
